SEROTONIN REUPTAKE INHIBITORS

A serotonin reuptake inhibitor which can be used in the treatment of depression and which has a decreased occurrence of unwanted side effects. The serotonin reuptake inhibitors are bi-functional organic molecules which combine serotonin transporter reuptake inhibition with serotonin (5-HT,such as 5-HT2A) receptor antagonism in one molecular entity. The serotonin-selective reuptake inhibitor (SSRI) homologue portion of the molecule shows an affinity to the serotonin reuptake transporter (SERT) and has antidepressant properties. The piperazine or piperidine portion of the molecule demonstrates an affinity to 5-HT receptors and restores the undesired side effects of SSRIs.

Synthesis and biological evaluation of 2-(4-fluorophenoxy)-2-phenyl-ethyl piperazines as serotonin-selective reuptake inhibitors with a potentially improved adverse reaction profile

Three new 2-(4-fluorophenoxy)-2-phenyl-ethyl piperazines, 1-(3-chlorophenyl)-4-[2-(4-fluorophenoxy)-2-phenylethyl]-piperazine 7, 1-[2-(4-fluorophenoxy)-2-phenylethyl]-4-(2-methoxyphenyl)-piperazine 8, and 1-[2-(4-fluorophenoxy)-2-phenylethyl]-4-(3-trifluoromethylphenyl)-piperazine 9, modeled after the potent antidepressant fluoxetine and coupled with several functionalized piperazines, have been prepared by chemical synthesis as selective serotonin reuptake inhibitors (SSRIs) with a potentially improved adverse reaction profile. Typical SSRIs, although very effective in the treatment of depression, still face the troublesome side effect of sexual dysfunction. A number of pharmacological agents-notably, drugs in the piperazine class-have been used to reverse SSRI-induced sexual dysfunction, and evidence for developing an improved SSRI by coupling a fluoxetine congener with the pharmacophore of a reversal agent holds promise. Preliminary data indicates that the hydrochloride (HCl) salts 10, 11, and 12 each exhibit single-site binding at the site of the serotonin reuptake transporter (SERT). However, each of the three compounds are much less potent than typical SSRIs, showing micromolar (μM) affinity for the SERT with IC50 values of 1.45 μM, 3.27 μM, and 9.56 μM, respectively. Further biological evaluation of compounds 10, 11, and 12 is needed before definitive conclusions can be made with regard to each compound's potential for use as an SSRI-type candidate which is devoid of sexual side effects. Nevertheless, the initial findings are quite encouraging, thus lending credence to the idea of hybridizing an SSRI congener with that of the pharmacophore of an agent known to reverse or treat SSRI-induced sexual dysfunction.
